SERVICE
ENGINE
SOON
Your Cadillac is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system
is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping
to produce a cleaner
environment. (In Canada, OBD
I1 is replaced by
Enhanced Diagnostics.) The SERVICE
ENGINE SOON
light comes on and a chime will sound to indicate that
there is a problem and service is required. Malfunctions
often will be indicated by the system before any
problem is apparent. This may prevent more serious
damage to your vehicle. This system is also designed to
assist your service technician in correctly diagnosing
any malfunction.
I NOTICE:
~
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine
is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least
10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following.
If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you just drive through
a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system dries
out.
A few driving trips should turn the
light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index).
Poor fuel quality will cause your
engine not to
run as efficiently as designed. You may
notice
this as stalling after start-up, stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling on acceleration. (These conditions may go
away once the engine is warmed up.)
This will be detected
by the system and cause the light to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

Downloaded from www.Manualslib.com manuals search engine Driver’s Side Temperature Button
The red and blue temperature buttons adjust the air
temperature coming through the system. Press the blue
button for a cooler setting or the red button for a
warmer setting.
Passenger’s Side Temperature Knob
With this feature, the right front passenger can control
the temperature of air for hisher own zone. The
passenger can select a four degree warmer or cooler
temperature from the driver’s setting.
To turn the system on, press the knob on the passenger’s
side armrest. Rotate the knob clockwise to increase the
temperature and turn counterclockwise to decrease the
temperature. Press the knob again
to turn the system off.
Outside Temperature Display
The outside temperature is always displayed when your
vehicle is running. You can change it from Fahrenheit to
Celsius by pressing
the ENG/MET (Englishlmetric)
button on the Driver Information Center (DIC).
The outside temperature sensor is located near the front
grille. The sensor can be affected by road or engine heat
during idling, slow driving
or when the engine is first
started after a short trip. In order to ensure proper
automatic climate control operation, the outside air temperature
display may not update as quickly as
expected. This is
to allow the air surrounding the outside
temperature sensor
to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned
off
and by vehicle speed.
Mode Controls
The AUTOBCON button automatically controls the
direction of air delivery for air conditioning and non-air
conditioning modes.
Automatic Operation
When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor, middle or windshield outlets. The fan speed
will vary as the system maintains the selected
temperature setting.
Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.

Downloaded from www.Manualslib.com manuals search engine To find your comfort zone, start with the 75°F (24°C)
setting and allow about 20 minutes for the system to
regulate. Press the red or blue temperature buttons
to
adjust the temperature if necessary. If you choose 60°F
(16"C), the system will remain at that maximum cooling
setting and will not regulate fan speed. If you choose the
temperature of
90°F (32"C), the system will remain at
that maximum heating setting and will not regulate fan
speed. Choosing either maximum setting will not cause
the system to heat or cool any faster.
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor
outlets.
As the interior temperature approaches a desired
setting, the blower speed will decrease.
To maintain
interior comfort, the aifflow may move to the instrument
panel air outlets and floor outlets (bi-level mode). On
bright sunny days in cold weather, the airflow may come
out of the air conditioning outlets (AC mode) to
maintain cornfort and prevent stuffiness. If
your vehicle is sitting out on a hot day and you have it
set on AUTO, the air will first flow out the floor air
outlets for a few seconds. That is normal. This is to
expel hot air from the air outlets. As the air is cooled,
the airflow will move through the air conditioning
outlets. If you start your vehicle with the fan setting on
HI, it will skip the air conditioning purge.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started.
As the coolant warms
up, the blower fan speed will gradually increase and air
will flow from the heater outlets, with some airflow to
the windshield to prevent fogging under most
normal conditions.
If you leave your vehicle, the system will remember the
control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas,
DEFROST will change
to automatic operation when the ignition
is shut off and
then turned back on.

Downloaded from www.Manualslib.com manuals search engine Manual Operation
RECIRCULATION: Press this button to limit the
amount of fresh air entering your vehicle. This is helpful
when you are trying to cool the air quickly or limit odors
entering your vehicle. In the AUTO mode, the system
will use recirculation
as necessary to cool the air.
Pressing the recirculation button will change the
operation to
a manual mode and the air will recirculate
non-stop. Press this button again to turn
off the
recirculation feature.
If you notice the windows fogging, press the
recirculation button to exit the recirculation mode.
OFF: Press this button to turn the system off. Fresh air
will continue to flow through the vehicle, and the
system will try to maintain the previously set
temperature. The outside temperature will show
in the
display when the system is off.
DEFOG: Press this button to divide the air between the
windshield and the heater outlets. This is useful when
fog appears on the windshield or side glass due to
sudden rain or snowy conditions.
AUTOECON: Press this button to switch between
AUTO and ECON. The ECON setting attempts to keep air
at a selected temperature, however, it does not remove
humidity from the
air. Use this setting in cold or cool weather to save fuel. The AUTO setting is used when it’s
warm outside and you need to cool the air in order to
maintain a selected temperature and blower speed.
# FAN SPEEDS: Press the button with the fan
symbol on it until AUTO is displayed
on the screen.
At this setting, the fan speed
is automatically controlled.
If it is cold outside, the blower may not run in the
maximum high fan speed right away. The system checks
the temperature
of the engine coolant to assure it is
warm enough to provide heat. When the engine coolant
is
warm, the controller allows the fan to gradually
increase to a higher speed. This prevents cold air from
blowing into the passenger compartment. If you want
the blower fan at a high speed, press the up arrow button
until you see HI on the display. If you want the fan
speed to be automatic, but you like the fan speed to be
higher than the AUTO setting, press the fan symbol
button until
HI AUTO is shown on the display. If you
want the blower
fan at a low speed, press the down
arrow button until
LO is shown on the display. If you
want the fan speed to run lower than the
AUTO
setting, press the button until AUTO LO is shown
on the display.
9 DEFROST Press this button to quickly remove
fog or frost from the windshield. This setting sends most
of the airflow to the windshield with only a small
amount to the floor outlets.
